p IMPROVEMENT IN AIR-ESCAPE FUNNELS.

TO 'ALL WHOM ITl MAY OONOERN:

Be it known that I, JOSEPH I. BEAUMONT, of St. Paul, in the county otRamsey, in the State of Minneseta, have invented a new and improved Mode of GivingVent to the Escape of Air from barrels, kegs, jugs, cans, demijohns, and other vessels of like character, while being filled with lfluids poured through a funnel, by means of a. funnel of a peculiar construction, as hereinafter described; and I do hereby declare that the following is a full and exact description of the funnell above mentioned, .reference being had to the accompanying drawings, and to the letters of reference marked thereon. l I I The nature of my invention consists in providing a funnel of a new and improved construction, containing within .itself` an air-chamber, through which the coniined air, `from the yvessel into which uids are being poured through the-funnel, may freely escape while the vessel is filling with the uid, thereby obviating the great inconvenience, trouble, annoyance, and loss of time very frequently experienced in the use of a commonfunnel, occasioned by want of the vent which my invention perfectly supplies.

To enable others skilled in the art of manufacturing such articles to make and use my invention, I will proceed to describe its construction and operation.

I construct a plain, simple funnel, such as is in common use, of any desiredl size andl material, with four, more or less, small openings or round holes in the sides ofthe body ofthe funnel, at any desirable distance from each other, and at a height above the neck of the funnel, which is, as near as may be, one-third (gi) of' the dis`l tance from the upper end of the neck -to the upper edgeoi' the body of the`funnel, as shown at Figure l, A and B, in the accompanying drawings. These openings or holes,-when thefunnel is completed, permit the free escapeofair from the air-chamber of the funnel.

I also make four, more or less, small openings oriround holes in the neck of this funnel, at any desirable j distance from each other, and as near as may be, say from one-quarter to three-quarters of'Y an inch above the lower end of the neck, as shown at d, Figures 1 and 2, in the accompanying drawings. i

There may also be other openings in the neck of the saidfunnel, situated above the said openings CZ, so as to permit and allow the ventilation to proceed with full effect and operation incase the said lowercpenings d shall become closed by means of the fluid in the vessel being filled bythe use of said funnel, and thus there may besuch graduatingv openings 'at othcr points along and upon the said neck of th'e said funnel, and thus and thereby carry on ventilation of' such vessel in case the lower holes become closed by the material being poured in the vessel to be filled. The saidaddtional or extra. openings may be made in said funnel-neck in the sameV manner and by the same means as the said openings' cZ are made. The said openings may be constructed at any desired distance apart from each other, either along the length .of the said neck of the funnel o1" upon the circumference thereof, as the case may require, takin-g care so to construct and arrange the same as that entire and complete ventilation -may go len until the entire cask or vessel be filled with thefluid or liquid desired to be putin the same, Anotwithstanding thelowcr'and nextlower 'ot' the said openings d'may become closed up by the tllingcr rising of material being poured into such vessel for the'purpose of filling the same, as hereinr seti'orth. i l

AThese openings or holes, when the funnel is completed, permit the lfree entrance of air, escaping from the vessel being filled, into the air-chamber of the funnel. v

'I-Iaving new the outer portion complete, I will proceed to construct and apply the air-chamber lor vent, which I do by constructing a little or inner funnel, B, similar. in construction to the large and outer one above described, except in that it has no openings or holes in its sides, either of its bodyor neck, and having'no wire running around its upper edge, as has the large outer funnel, and as iscommonly the case with ordinary funnels, to give a nish and add strength to the upper edge. This little and inner funnel I construct with four l upright wires, or more, if required by the size o f the funnelr and the said wires are each made fast tothe outer.

side of the inner funnel, (soldcredfast'if the tunnel is of tim) and at any desirable distance from each other, and extending up from the lower end et' its neck, to a pont'n the outer sides ot' the body, as near as may be,

three-quarters of an inch or more above the neck of the funnel, as shown at B and C of Figure 3, in the accompanying drawing, o-r as may be desired.

` This little and Ainner funnel I construct of suoli a size that with its aforesaid wires attached it shall correctly iit into the large and outcr funnel, so that the lower end of the neck of the little and inner funnel shall project below the lower end of the neck oi' the outer one, as near as may be, one-quarter tothree-eighths of an inch or more, and the upper edge of its bodyl shall t to the body of the outer funnel one-eighth to one-quarter of an inch or more above the aforesaid small openingsror round holes in the body of the outer funnel, and there b c tightly secured, or soldered if the material be tin, or, if the funnel is oi some other matcrial, brazcd, or otherwise properly made tight.

The funnel is non complete, substantially'as shown in the'accompanying drawings.

The air-chamber between the inner and 'outerA funnel is arranged and preserved by the said wires d, as described and shown at a, iig. l, and the escaping airfrom the vessel (into which fluids are poured through the funnel) will pass into the air-chamber a, fig. l, between the wires CZ, and through the said small holes d, iigs. 1 and 2, at or near or above the low-er end of the neck of the outer funnel, as the case may he, and thence through the air-chamber a, and thfenee out of the said small holes c, figs. 1 and 2, in sides of thc body of the outer funnel.

It makes a most perfect vent for any vessel which requires the use of a funnel in filling.

By constructing a funnel substantially as shown in and by the accompanying drawings, it will appear that no dust or ilies, in case of the use of molasses for filling of asuitable vessel, or other matter or other material can enter said air-chamber a, and thus and thereby 'lill or obstruct the same, so as. to prevent the escape of the air from such vessel through and by the means of the said openings hereinbefore described and set forth. The

,said inner funnel B must always be constructed substantially as'shown at fig. 3 of the accompanying drawings,

which is also in all` cases pnt upon the inner side of the said'outer `funnel A, substantially as shown at fig. 1 of said drawings, and, beingthus constructed and arranged, the said inner funnel may beremoved from the said outer one for the purpose of repairs, or for the purpose of cleansing the said |air-chamber a, or 'the respective inner and outer funnels A and B, after which the same may be put together again ready for use, substantially as shown at said fig. 1, and, therefore, the drip ofthe funnel will not obstructsaid air-chamber, or soil the outer part of the said outer funnel A; also graduating the process of ventilation as the said Vessel is being lled in thc manner aforesaid. v

Thefunnel is simple, and not very expensive in construction. lIt is compact, and not liable to get out of order.

I I claim ,the combination of the inner funnel B, having thereon the wire rods b, with the outer funnel A, containing theapertures c and d,-thc. whole being constructed and arranged in the manner and for the purposes substantially as herein described andl set-forth. i y
